ATTORNEY United States Patent 3,374,781 PRESSURE VESSEL Maurice Bramson,16 Woodcrest Road, Kings Point, N.Y. 11024 Filed Oct. 13, 1965, Ser. No.495,435 3 Claims. (Cl. 126-369) ABSTRACT OF THE DISCLOSURE A vesselhaving alongitudinal body shell, said body shell including a steampressure chamber and a condensation chamber, said chambers beingtandemly arranged, said condensation chamber being at atmosphericpressure when said pressure chamber is above atmospheric pressure,partition means sealingly separating said chambers, and condensationmeans mounted within said condensation chamber, said condensation meanshaving an inlet and an outlet opening, one said opening being incommunication with said pressure chamber, the other said opening beingin communication with the atmosphere, and valve means for regulatingfluid flow through said condensation means.

This invention relates generally to steam pressure vessel apparatus andmore particularly to the combination of such apparatus with condensationmeans adapted to preclude discharge of steam directly to the atmosphere.

More specifically, the primary object of this invention resides in theprovision of pressure and condensation chambers, both of which areformed integrally of a common longitudinal body shell.

Another object of the instant invention is to provide an apparatus whichincludes a pressure and a condensation chamber both housed within alongitudinal jacket.

A further object of the present invention is to provide apparatus of theforegoing character which is capable of substantially obviating thedischarge of steam into the atmosphere and in so doing making possiblethe reuse of water which would otherwise be lost.

Another general object of this invention resides in the provision ofsterilization or cooking apparatus as described herein which iseconomical of manufacture and highly efficient in use.

Other objects and advantages of the present improved pressure apparatuswill be set forth in part hereinafter and in part will be obviousherefrom, or may be learned by practice of the invention, the same beingrealized and attained by means of the structure defined and pointed outin the appended claims.

The accompanying drawings referred to herein and constituting a parthereof, illustrate embodiments of the invention, and together with thedescription, serve to explain the principles of the invention.

FIGURE 1 is a side elevational view of the preferred embodiment of theinvention;

FIGURE 2 is a top plan view thereof;

FIGURE 3 is a view of the invention taken along line 3-3 of FIGURE 1;

FIGURE 4 is a front elevational view of the invention; and

FIGURE 5 is a modified embodiment of the invention.

In accordance with the foregoing, the instant invention is essentiallydirected to the novel arrangement and combination of a pressure chamberand a condensation chamber, both chambers being included within a commonlongitudinal body shell illustrated in the accompanying drawings.

With reference to FIGURE 1, the vessel shown is comprised of alongitudinal body 1 which includes the outside shell 2 of steam pressurechamber 4 and condensation chamber 6. It will be understood that thepressure condensation chambers, may within the contemplation of thisinvention, be separate although joined whereby the outer shells thereofwill become united to form a continuous longitudinal body shell. Or aswill be described hereinbelow following with respect to FIGURE 5, thechambers may be arranged in tandem, a separate outer longitudinal bodyshell being applied about the pressure chamber and extending therefromto form the shell of the condensation chamber.

Pressure chamber 4 is provided with a door 8 which may be of anysuitable construction, and a heating element 10 is located on the bottomof the chamber. In operation the heating element 10 serves to generatesteam by heating water in which it is immersed. An outside steam source,however, may be utilized wherein the use of a self contained heaterwould not be required.

The condensation chamber 6 is provided with an opening 12 where throughwater may be poured to fill the chamber. A door 14 is shown withapertures 16 therein, said door, inter alia, serving to silence thenoise occasioned when steam enters the chamber as described hereinbelow.Wall 18 partitions the chambers, and may be a single common wall asshown in FIGURES 1 and 2 or may be formed of two separate walls in theevent chambers 4 and 6 are separate but united to form a continuouslongitudinal body structure. Two separate partition walls withinsulation material, a vacuum or dead air therebetween may also be usedto separate the chambers.

Condensation coil or condensation means 24 is mounted within thecondensation chamber 6. Said condensation means may be a tubular coil asshow nor any other suitable condensing unit which effectuates heatexchange between steam or other fluid passing therethrough and theambient medium. The coil illustrated is provided with an inlet opening26 and an outlet opening 28, the inlet opening being in communicationwith the pressure chamber 4 as shown and the outlet opening being incommunication with the atmosphere as shown. Valve 30 is connected asshown to said condensation coil to enable positive shut-off of fluidflow through said coil between said pressure and condensation chambers.Valve handle 32 enables the user to regulate the fluid flow rate throughthe valve. Stand 34 is provided to support the vessel.

With reference now to FIGURE 5 of the drawings, the alternate embodimentof the invention illustrated therein includes pressure and condensationchambers 36 and 38, respectively, longitudinal body shell 40 beingsuperposed around pressure chamber 36 and a portion of said body shellbeing arranged to extend beyond said pressure chamber to form the sidewall of said condensation chamber. Said extending portion of said bodyshell is closed by end wall 42, the latter being spaced from wall 20 ofsaid pressure chamber.

In operation, the pressure chamber is filled with a predeterminedquantity of water, valve 30 being in the shut-ofl? position. The door 8is closed and heater 10 is energized. The water within said chamber willboil and transform to steam to build up pressure within chamber 4. Upontermination of the sterilization or food cooking period, valve 30 isturned to the open position whereupon steam and remaining water willpass through coil 24, which is preferably submerged in water, and thesteam will be transformed to the liquid state. The liquid thus formedwill be added to the water previously present in the condensationchamber. After the steam has been discharged from the pressure chamber,valve 30 is closed. Should it be desired to re-fill the pressurechamber, the

valve, when opened, will permit water to flow through the coil and intothe pressure chamber. Thus, the water previously condensed may be reusedfor subsequent pressure cycles.

Although exemplary embodiments of the combined pressure-condensationchamber apparatus have been described, it will be understood that withinthe purview of this invention various changes may be made in the forms,details, proportions, instrumentation of the vessel and arrangement ofparts, the combination thereof and mode of operation, which generallystated consists in a device capable of carrying out the objects setforth, as disclosed and defined in the appended claims.

What is claimed is:

1. A vessel comprised of a longitudinal body shell, said body shellincluding a steam pressure chamber and a condensation chamber, saidchambers being tandernly arranged, said condensation chamber being atatmospheric pressure when said pressure chamber is above atmosphericpressure, partition means sealingly separating said chambers,condensation means through which fluid can flow, said condensation meansbeing mounted within said condensation chamber, said condensation meanshaving an inlet and an outlet opening, one said opening being incommunication with said pressure chamber, the other said opening beingin communication with the atmosphere, and valve means for regulatingfluid flow through said condensation means.

2. A vessel as set forth in claim 11 wherein said pressure andcondensation chambers are integrally formed of said longitudinal bodyshell.
